Chainguard Container for dask-gateway

A multi-tenant server for securely deploying and managing Dask clusters.

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/dask-gateway:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Compatibility Notes

Chainguard's Dask Gateway container is comparable to the daskgateway/dask-gateway image maintained by Dask. Like most of Chainguard's container images, the Dask Gateway image was designed for minimalism and does not include things like a shell or package manager.

Getting Started

To get started, first create a pair of environment variables to hold the names of the Helm release and the Kubernetes namespace, respectively:

RELEASE=dask-gateway
NAMESPACE=dask-gateway

This example uses the name dask-gateway for both variables, but you can name the Helm release and Kubernetes namespace anything you'd like.

Next, you need to set up a values file. The Dask Gateway Helm chart offers many configuration options allowing you to create a setup that suits your exact needs. You can use the default values.yaml file as a basis for your own. The default file also includes explanations for many of the available configuration options.

Be sure to edit the values.yaml file to point to Chainguard's Dask Gateway image instead of the upstream alternative:

  backend:
    image:
      name: cgr.dev/ORGANIZATION/dask-gateway
      tag: latest
      pullPolicy:

Next, install the Dask Gateway Helm chart by running the following command:

helm upgrade $RELEASE dask-gateway \
    --repo=https://helm.dask.org \
    --install \
    --namespace $NAMESPACE \
    --create-namespace \
    --values values.yaml

Once the resources have been created, run the following command to ensure that the services are running:

kubectl get service --namespace dask-gateway

NAME               	TYPE       	CLUSTER-IP  	EXTERNAL-IP  	PORT(S)    	AGE
api-dask-gateway   	ClusterIP  	10.96.107.183   <none>       	8000/TCP   	134m
traefik-dask-gateway   LoadBalancer   10.96.236.132   146.148.58.187   80:31487/TCP   134m

Additionally, run the following command to ensure the daskcluster CRD was installed:

kubectl get daskcluster -o yaml

apiVersion: v1
items: []
kind: List
metadata:
  resourceVersion: ""
  selfLink: ""

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
